The Question is: I am trying to "resurrect" a microvax 3400 I have, which contains the following boards: M9060-YA Load Module for BA123 TQK70 M7559-00 TK70 Tape Unit Controller CXY08-M M3119-YA 8-Line asynchronous multiplexer IEQ11-SA M8634-PA Communications Controller VCB-02 M7168-00 4 plane color bitmap module VCB-02 M7169-00 4 plane video controller module MS650-AA M7621-A 8Mbyte Ram MS650-BA M7622-A 16Mbyte Ram MS650-BA M7622 16 Mbyte Ram KA640-AA M7624-CA Microvax 3400 CPU I also have an R23RF-A2 disk chassis. The mircovax has no internal hard drives. What hard drives will fit the microvax and the R23RF-A2? TP Robson The Answer is : The MicroVAX 3400 series uses Integrated Storage Element (ISE) drives. These are the RF-series disk drives and the TF-series tape drives, and specifically the RF3x series and the RF7x series disk drives. The BA213 S-box enclosure is the most common box for the MicroVAX 3400 series, and has room for two RF-series disks and TF-series tape or (with a TQK-series Q-bus controller) TK-series tape. These DSSI systems and enclosures are not generally set up for use with SCSI devices. The R23RF is a comparatively rare(r) rackmount enclosure for removable storage element (RSE) RF-series disk devices -- non-removable devices do not fit in this enclosure. The R400X series DSSI pedestal enclosures were rather more commonly seen, and (like the BA213) supports internal RF-series disk drives. Later DSSI-capable systems were regularly configured with an HSD-series DSSI to SCSI adapter, and with external SCSI storage. Here are some of the more common RF-series disk devices: Capacity Disk per drive BUS Interface / Controller Notes ---------- ---------- -------------------------- ------- RF30-RA 150 MB ISE 1 x RF30 disk, RSE RF30E-SA 150 MB ISE 1 x RF30 disk RF30C-xx 300 MB ISE 2 x RF30 disks RF30C-xx 300 MB ISE 2 x RF30 disks, RSE RF30C-xx 800 MB ISE 2 x RF71 disks, RSE RF31 381 MB ISE (DSSI) RF71-xx 800 MB ISE 2 x RF71 disk RF71x-SA 400 MB ISE 1 x RF71 disk RF71x-RA 400 MB ISE 1 x RF71 disk, RSE RF71x-xx 800 MB ISE 2 x RF71 disk, RSE RF72 1 GB ISE RF73 2 GB ISE
